Kubectl Plugins and Krew

Krew helps you discover and install kubectl plugins on your machine.

There are a lot of kubectl plugins you can install and use to enhance your Kubernetes experience.

Let’s get started:

1. Install and set up Krew on your machine.

2. Download the plugin list:

kubectl krew update

3. Discover plugins available on Krew:

kubectl krew search
NAME                            DESCRIPTION                                         INSTALLED
access-matrix                   Show an RBAC access matrix for server resources     no
advise-psp                      Suggests PodSecurityPolicies for cluster.           no
auth-proxy                      Authentication proxy to a pod or service            no
[...]

4. Choose a plugin from the list and install it:

kubectl krew install access-matrix

5. Use the installed plugin:

kubectl access-matrix

6. Keep your plugins up-to-date:

kubectl krew upgrade

7. Uninstall a plugin you no longer use:

kubectl krew uninstall access-matrix

This is pretty much all you need to know as a user to use Krew.
